At long last, the transformation of your mobile device (don't call it a cell phone) into digital Swiss Army knife is complete. There's the phone part, the camera, the audio player, the GPS, the phaser... and now the trainer. With sites like AllSportGPS.com ($7 a month), SportsDo.net ($9.75), and BimActive.com ($10), you can remotely log your workouts via satellite. While you're running or biking, the site's busy uploading what your GPS is telling you: speed, distance, altitude, route, and averages. Back home, study your stats, download sessions for training against yourself later, and share your times and Google Earth–tagged routes with other users. Now get out there and beat that blip.
